BUTCHERS REFRIG-ER-ATOR, DISPLAY CASE. I

Application filed. .Tune 1, 1925. Serial No. 34,115.

To all whom it may concern Be it known that I, ALoNzo EooLnsroN,

a citizen of the United States, residing at Rochester, in the county of Sangamon and State of- Illinois, have invented a new Butchefls Refrigerator Display Case, of

which the following is a specification.

This invention relates to a type of refrigerator display cases adapted-to be used in butcher shops and places of the like for keeping meats and other foods cold while on display.

()ne of the purposes of this invention is to providea refrigerator meat display case to be economically manufactured and secure a maximum of efiiciency in keeping meats cool while on display instores. butcher shops and the like and accomplish this result in the most economical manner.

A further object of my invention is to provide a hutchers refrigerator display case of the character hereinafter described that will protect the ice to a maximum extent, that will keep the water off the floor of the display compartments, that will enable the briny: water melted from the ice to help in melting the ice steadily before such water leaves the ice container to provide an ice container in a display case supported on rollers and other means adding to the con veniences of refilling the same and to provide a. refrigerator display case adapted to keep the air therein cold to the extent of an average daily'temperature of from 5 to degrees below freezing thus securing a maximum of benefit from the ice ata minimum cost for the ice. v

A further object of my invention is to provide a display case of the character hereinafter described having a drain basin disposed in the floor thereof in which position the same is adapted to receive the drainage from the drip pans ofthe ice compartments; which drain. basin is pro vided with an air trap to keep out the warm air; and a refrigerator display case having walls and faces and tops provided with a plurality of layersof material which will aid in keeping the icetoa low temperatu I annexed:specification, recited in theclaim and illustrated in .the accompany ng. dra as n h h i e refe ees senses are I attai'nithe objects of myinvention abo e mentioned in the structure describedin t e cate the same structural figures.

Referring to the figures: Figure 1, is a perspective of the display case of my invenparts in the several tion showing the top, front and endviews.

same drain basin shown in its relative position to the floor of the refrigerator.

Figure 13 is a perspective of the air trap adapted to be seated in an inverted position over the central drain tube of the drain basin where the side holes in the air trap provide an outlet for the water. draining away while the top of the case is adapted to provide an air trap to prevent warm air from coming into the refrigerator through the drain. Fig. 1a is the truck for the ice container,

Fig. 15 is a detail of the wall structure.

Referring now to the several details of my invention which are designated by nu1nerals and which numerals indicate the same structural parts in the several figures I shall attempt to point out the relation of the several parts to the whole structure.

In the drawing numerals 1-' and -2- refer to the end compartments respectively, which are adapted to be used as ice compart ments. Numeral 3- indicates the display compar ment in which meats and other perishables are normally kept for display and protection. A pair or ice containers and -stwhen filled with ice and within the ice compartments are seated in a truck -12 mounted on rollers 39 and resting on tracks -11 adapted to normally support the ice containers.

For instance, when it is desired torefill the ice containers aand -4J- the butclr er opens the rear outer door 6 and -6 oi": the ice compartment and then opens rear inner door and -5-- of the ice compartment by pulling on handle 13-. This door is pivoted along the bottom edge and is opened down to ahorizontal position where it may be supported A rubber sleeve 38 is provided in handle 18 which is adapted to prevent this handle from slipping on the floor when this door is let down to a horizontal position supported thereon.

Truck 12 on its rollers 39 normally rests on track 11 in the ice com partments where this truck supports the ice container -eland -ft in the respeclive ice compartments and when inner door --5 and -5 is resting in a horizontal open position it is adapted to provide a track support for the convenient removal of the ice container 4 and when the container is pulled out'of the ice'compartmentand refilled. It will therefore be seen that when the ice container is being, refilled the inner i0o1- 51 and thns provides a tableor sl'ielf forthe ,ilc'e containers support and is found to. bej e spect ally convenient and sanitary sincleit has rned up ge 9-"t. 0. 7.. flanges integral with the door whichielft adaptedt0 .,Clrai n any'water dripping from ecpntai Q15, bask Jet-91th? ifl ficemp rip Attention is called to the fact that ice containers are provided with a drain tube -1 l and l lwhich are securely attached to the bottom of the ice container over in a corner where they will not be in the way and there adapted to normally drain the ice container after holding the briny water therein from the melted ice to a suitable level "for the best melting effect on the ice before the briny water is permitted to drain oil at top of the tube.

Access to the display compartment is convenient through either of the rear doors -T8-9 or -10. A drain basin adapted to be built into the floor -3T ot the refrigerator. A pair of drip pans l5 and -16 are adapted to re ceive the dripping water "from the ice conr tainers respectively and from the drip pans the drainage is carried through drain tubes 17 and -l8 respectively to the drain basin 20-.

Drain basin 20 has an integral central tubular drain pipe projecting upward and downward from the floor of the drain basin. The downward projection is threaded for further drainage connection for carrying away the drainage while the upward projection terminates at a level approximately half way between the floor of the drain basin and the upper edge of the periphery of the main drain basin. An air trap '22 comprising an inverted cup. having a plurality of apertures ii-O and adapted to be normally set down over coir tral drain tube -2l in the drain basin. in which position air trap 22" is adapted to prevent warm air from coming into the refrigerator through the drain tube and also shut out odors, coming from the drain tube carrying away the drainage while at the same time the openings in the air trap being positioned in elevation, normally about half way between the top of the central drain tube and the floor of the drain basin are adapted to pass the draining water at a level that permits sediment to settle in the floor 01, the basin and not pass out through the holes in the air trap and cause the same to become stopped up.

The ice containers -4 and -'-larc provided with protective apertures in the sides for aiding in circulating the cold air from the ice. The display compartment is provided with horizontally disposed shelves -i25' and 26 for the support of meat trays. v

'lheend walls 27. and -2S of the respective ice. compartments, the floor walls jt29 .a' nd .30 and the top walls -31? ant 32 .respectively of the ice. compartiments are consttuctfidtof insulating mate- .Snbst iii- 11. and i su a ina tl1e;.. maxi1nuinof ars and 6- are likewise built of a similar combination of substantial insulating materails, and each also has a collapsible shelf l-land -4;1 for the convenience of the butcher.

For instance: These doors and the walls for the ice compartment and the rear doors of the display compartment and the bottom of the refrigerator have an inner and outer wood panel and having between these panels a heavy layer or cork and a sheet of moisture proof composition paper, another substantial layer of cork and a second sheet of water proof composition paper.

Referring to the display compartment, attention is called to the fact that the transparent walls on the top and in the front designated by numerals 3334-35 and 3G-- are constructed of four layers of plate glass, each layer spaced from the other to provide a suitable air space between, and adapted to provide a mximnm of protection against allowing the air within the refrigerator from becoming heated by conduction from the warm air outside. which in ordinary refrigerators with only one thickness of glass can not be accomplished to a satisfactory extent.

It will be seen in the abovedescription that every effort is made to prolong the frozen state of the ice by keeping the temperature down in a most practical way, and it has been found, as a result of numerous tests made with this refrigerator that it effectively keeps the air therein comparatively dry, and maintains the temperature have explained the preferred embodiment of my invention.

I. aving thus described the nature of my invention, what I claim is:

In a refrigerator having a display compartment and an ice compartment, an ice container and support comprising a container on trucks fixed tracks within the ice compartment for the trucks, an outer deer and an inner door for the ice compartn'ient; said inner door provided with spaced rails aligned with said tracks and a U-shaped handle for said inner door, adapted to provide optional support there a for when the door is open; whereby the ice container ,inay be optionally removed from said ice compartment by rolling it out upon said rails of the opened inner door when it is desired to refill the ice container.

In witness whereof I hereunto set my hand and seal this 13th day of April A. D.
